All things philatelic will be celebrated at the annual Rockingham Stamp Show and Auction on Sunday, where an original Great Britain Penny Black stamp, dating from 1840, will be the sought-after door prize.
Club president Dennis Penfold said he began collecting stamps more than 60 years ago when his dad handed over his collection.
He said the Philatelic Society of Rockingham and Kwinana Districts (PSRKD) had about 45 members and attracted about 30 of those to monthly meetings, where brains were kept active with myriad themes that provided an insight into our world and its nations.
Mr Penfold said the internet, and particularly trading website ebay, had opened up the stamp collecting movement, with an average of more than 500,000 stamps for sale online at any one time.
On Sunday, nine stamp dealers will be on hand and more than 500 lots will be up for auction, with reserve prices starting at $5.
The annual show is a joint project of the PSRKD, the Fremantle and Districts Philatelic Society and the Mandurah Philatelic Society.
